This patch makes the dummy_hcd driver create separate platform devices for
the emulated host controller and emulated device controller. This gives a
more accurate simulation and will permit testing of situations where only
one of the two devices is suspended.
This also changes the name of the host controller platform device to match
the name of the driver. That way the normal platform bus probe mechanism
will handle binding the driver to the device.

This patch makes some cosmetic changes to dummy_hcd:
Minor alterations of comments and whitespace.
Replace USB_PORT_FEAT_xxx with USB_PORT_STAT_xxx. This is
appropriate as the values are stored in a status variable
and they aren't feature indices. Also it allows the
elimination of a bunch of awkward bit shift operations.

Partial OTG support for dummy_hcd, mostly as a framework for further work.
It emulates the new OTG flags in the host and peripheral frameworks, if
that option is configured. But it's incomplete:
- Resetting the peripheral needs to clear the OTG state bits;
a second enumeration won't work correctly.
- This stops modeling HNP right when roles should switch the first time.
It should probably disconnect, then set the usb_bus.is_b_host and
usb_gadget.is_a_peripheral flags; then it'd enumerate almost normally,
except for the role reversal. Roles could then switch a second time,
back to "normal" (with those flags cleared).
- SRP should be modeled as "resume from port-unpowered", which is
a state that usbcore doesn't yet use.
HNP can be triggered by enabling the OTG whitelist and configuring a
gadget driver that's not in that list; or by configuring Gadget Zero
to identify itself as the HNP test device.

This patch changes the host controller drivers; they no longer need to
register their root hubs because usbcore will take care of it for them.

This patch changes the HCDs that used the old hub_set_power_budget call,
making them use the new hcd->power_budget field instead.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
